Otherwise, look at your budget, what you really want, what each machine offers, local support, and if you take it for retreats or sew-ins can you carry it without difficulty. Try each out and see which you bond with the most - which one yuo don't have to go back to the manual to see how to work it because it is intuitive to your way of thinking.
I had a Brother which I di use for trade in on a Pfaff because the Brother was way too heavy and all the weight was on one side so I had great difficulty lifting it.
